Arkansas quarterback Ryan Mallett has left the game due to an apparent injury. What that injury is, nobody knows exactly. Following an Auburn touchdown -- that wasn't really a touchdown -- the Razorbacks came back on the field with Tyler Wilson under center. CBS's Tracy Wolfson tried to find out what the problem with Mallett was, and where he was, but Arkansas refused to tell her anything.

According to the Auburn sideline, however, Mallett has gone back to the locker room with what they say is a knee injury. How accurate that report is, we don't know. What we do know is that without Mallett on the field, Arkansas is in serious trouble.

The first series with Wilson under center resulted in a blocked punt that set up another Auburn touchdown to give Auburn a 24-14 lead.

Hopefully there will be more information on Mallett's injury following halftime. When we learn more about what's going on, we'll let you know.

UPDATE: Before heading into the locker room at halftime, Bobby Petrino told Tracy Wolfson that Mallett had "hurt his head." When asked if it was a head injury Petrino responded, "I don't know." Apparently his head is hurting too.

UPDATE: Bobby Petrino confirmed that Mallett has suffered a concussion and will not be returning in the second half. Tyler Wilson will continue to play in his place.

Breakfast

Yes, the morning menu is still incredibly light this week. You'd think I'd be beyond complaining about it at this point since it's been this way all season, but I assure you, I am not above complaining about anything . Though this Michigan State and Illinois game isn't as unfulfilling as it may seem at first glance.

Michigan State is 6-0, after all, and coming off of a very big win against Michigan. Illinois has also played well lately, with a win not many saw coming on the road against Penn State last week. Also, let's not forget that the Illini gave Ohio State a very tough time in Champaign a few weeks ago.

There's enough cause to believe that another upset may be in the works this weekend. First of all, Michigan State is coming off that Michigan win, and there could be a letdown this weekend. Second, it is Michigan State. Completely unexpected losses at home against teams they should beat after getting off to a good start to the season wouldn't exactly be a new phenomenon for the Spartans.

Side Orders: If you don't get the Big Ten Network, and don't have the choice of watching Michigan State and Illinois between Ro-Tel and Velveeta commercials, there are other options. Florida State and Boston College square off in Tallahassee, or you could tune in to what could be Tim Brewster's last game when Minnesota takes on Purdue. Of course, if you want to watch that game I'd suggest spending three hours talking to some sort of counselor instead. Maybe you should watch Syracuse and Pitt instead, just to see if you should actually take this Syracuse team seriously.

Now that Alabama has lost, it leaves the door open to a couple of teams in the SEC West. Auburn is one of them. Arkansas, who has already lost to Alabama, has an outside chance, but to make the most of it, a win over Auburn is a must have.

Of course, even if there wasn't so much on the line for both teams in this game, I'd recommend tuning in just to watch Cam Newton and Ryan Mallett face off. In other words, expect a lot of points, and what could turn out to be a very exciting, back and forth affair.

Auburn's pass defense left a bit to be desired against Kentucky last week, and don't think that Bobby Petrino didn't pick up on a few things when watching the game tape. The Auburn defense is going to need to play very well if the Tigers want to leave this one with their perfect record still intact.

Side Orders: There are a couple of other dishes available in the afternoon, including the one that's often best-served cold, which Nebraska is hoping to give Texas tomorrow afternoon. There's also Michigan and Iowa in the Big House, which will be a defining game for the Wolverines. We find out if Michigan is either a good team that lost a tough game against a rival last week, or it's still the same old Michigan we've grown accustomed to the last few years.

Dinner

Main Course - #18 Wisconsin vs. #1 Ohio State - 7pm - ESPN

It's been a while since the Buckeyes found themselves ranked as the best team in the country, but if they're not careful, it's not going to last long. The Buckeyes have gotten off to a 6-0 start this season, but this is the first real test they'll have faced. Yes, Miami was a tough game, but that was at home and Miami has proven to be pretty average this season.

This is the road, at night, at Camp Randall Stadium. Ohio State's defense hasn't faced a punishing ground game like it'll be seeing against Wisconsin with John Clay and company. Ohio State has only ventured outside of Columbus once this season, and that was what turned out to be their worst game of the season against Illinois.

And trust me, it's a lot easier to win in Champaign than it is in Madison.

Side Orders: Kentucky nearly knocked off Auburn at home last week, and it will try to do this same this week when it hosts South Carolina. The Gamecocks are coming off their biggest win ever, so a let down could be in order. There's also Florida looking to end its two-game losing streak taking on Mississippi State and old friend Dan Mullen, and the Crimson Tide look to take out their frustrations from last week against Ole Miss and its new mascot.

Late Night Snack

Oregon State may have had some troubles with non-conference foes like TCU and Boise State, but it's off to a nice start in conference play. They look to improve to 3-0 in the Pac-10 when they head to Washington to take on the Huskies Saturday night on ESPN.
